It's trying to load org.eclipse.yasson.JsonBindingProvider as that's the hard-coded default provider that's used by JsonbProvider when the ServiceLoader mechanism doesn't provide one.
We might be able to do something similar to what we've done for Bean Validation with a conditional on resource:
@ConditionalOnResource(resources = "classpath:META-INF/services/javax.json.bind.spi.JsonbProvider")
We'll need something more complex if Yasson relies on being the default provider and doesn't have a META-INF/services file.
